Uses
Uses & Benefits
  • Currently known uses of Ununseptium metal are limited to research purpose only.
  
  • Thallium is a toxic metal and hence it has limited uses. Thallium metal is mostly used for producing photoelectric cells.
  • In thermometer’s mercury alloy has 8% of thallium, as it has a melting point lower than 20°C.
